Introduction
It is important that people know more about GM, so we will show you. You will know what is GM, who started with the experiences, the advantages and disadvantages, some curiouse facts, exemples of animals and food that have been genetically modified, which are the countries that produce more GM food and a statistic about the opinion of Romanians people about it.
• Genetic engineering, also called genetic modification, is a process in which genetic material is changed to make possible the production of new substances or new functions to animals, plants or humans using biotechnology. Per example the crops can be resistant to cold, pesticides and diseases. Or eliminate human hereditary diseases and change their physical characteristics.
Gregor Mendel
• Gregor Mendel (1822-1884) was borned in Austrian Empire and he was a scientist and friar which gain fame as the founder of the new science of genetics. He made experiences with plants variation, implanting gens of one organism to another starting the genetic modification process.
Advantages
Some people say that it can: • cure infertility
• save endangered species• replace a dead son and adoption
• save lives• more medical treatments
• DNA analysis• bring immortality
Disadvantages
• This food doesn’t have a label• Mass produce human being• Use and abuse of genetic data
• Nobody knows the effects in the long run• Instability of the ecosystem• Ethical and moral issues• Endanger genetic diversity
Facts • Many people lie about the effects of GM many times
because of economical interest. But here are some true facts:
• The mutilation can lead to many unexpected changes like poor crop performance, alteration in the nutritional content, toxic and allergenic effects.
• It doesn’t reduce pesticide, it even increase.• It doesn’t increase crop field potential but it makes it worst
by destroying the needing soil nutrients.• Creates serious environmental problems, killing important
animals.• It doesn’t help solve climate change because of the
increase of quimicals• It won’t help to end up with the world hunger, the food is
just bad distributed.

Genetic modification in animal
The Enviropig, is a pig more environmentally friendly by the decreasing the phosphorous.
• COWS PRODUCE HYPOALLERGENIC MILK• In New Zealand, the cow produces milk almost entirely free of a
protein which causes allergies. And the bigger size of the cow that provides more met.
GLOW DARK PIGSCientists of Taiwan, created three pigs that glow in the dark. Their objective was use the glow dark pigs to study the combat of human diseases.

Other products
The banana vaccine – To fight against diseases such as cholera and hepatitis.
Salmon that grow faster – To feed more population and good by his properties.
Bigger, longer-lasting tomatoes - These are engineered to produce tomatoes that can remain fresh for longer and be bigger.
Cows that fart less - They have been produced to fight the deleterious effects that cow flatulence can have on the environment.
Conclusion
Now you know more about this procedure. The main creator of GM was Gregor Mendel in the XIX century. And we could see the good things about this modern tecniques, but there are also a lot of uncertaintly and problems that could rise because of this.America is the continent that produces more GM food. And you can be eating a lot of it without even knowing though most of the people doesn’t agree with GMO’s.
